PURPOSE:To save parts cost, assembling cost and the like in a push button used for an electrophtographic copying machine and the like by operating a common switch member installed on the same substrate through an actuator consisting of parts whose heights are different by means of the push button of the panel surface where the positions of the operating section are different in height. CONSTITUTION:An operating part is composed of a push button always used when a user uses an electrophotographic copying machine, a panel face 10 with display, a push button used with a little frequency, a panel face 20 with display, a transparent cover member 30 manually opened and closed and adapted to cover the face 20. A copy button, ten key, automatic returning button, and cassette selection button are provided on the face 10. A magnification selection button, buttons for enlargement and reduction, and copy density turnover button are provided on the panel face 20. The respective faces of the face 20 and member 30 are then made with the same appearance and the same height for improving the controllability, and the face 20 is located below the face 10 by the thickness of the member 30. It is thus possible to use an actuator in common with the stepped control panel face. |
